Why common mode inductance can prevent EMI? To figure out this, we need to start analyzing the common mode inductor.
Common mode inductor filter circuit, La and Lb is common mode inductor coil. The two coils are wound around the same core, the number of turns and the phase are the same (reverse winding).. So when the circuit in the normal current flows through the common mode inductor, current in the same phase around of inductance coil produced reverse magnetic field and cancel each other out, when normal signal current is mainly affected by the effects of coil resistance (and a small amount due to leakage inductance caused by damping); when there is a common mode

Flow meridian circle, due to the common mode current in the same direction, in the coil produces the same direction of the magnetic field and increasing the coil inductance, coil performance is high impedance and produce strong damping effect, in order to attenuation of common mode current, achieve the filter. [2]
In fact, the filter circuit is connected to the interference source, and the other end is connected with the jamming equipment, La and C1, C2 and LB constitute two groups of low pass filter, can make the line of common mode EMI signals is controlled at a very low level. The circuit can inhibit the external EMI signal, and can attenuate the EMI signal generated when the line itself, can effectively reduce the EMI interference intensity.
Domestic production of a small common mode inductors with high frequency noise suppression countermeasure and the common mode choke flow coil structure, signal attenuation, small volume, easy to use, with a balance of degree good, easy to use, high-quality, and other advantages. Widely used in the double balanced mixer, multi frequency transformer, impedance transformer, balance and unbalanced conversion transformer... Etc..
And a common mode inductor filter / EMI filter inductor with ferrite core, the bifilar winding, noise suppression best countermeasures, high common mode noise suppression and low differential mode noise signal inhibition, low differential mode noise signal suppression of interference sources, in the high speed signal is difficult to be deformed, small volume, with the balance degree good, easy to use, high quality advantages. Widely used in the suppression of electronic equipment EMI noise, personal computer and peripheral devices USB line, STB, IEEE1394 DVC line, LCD panel, low-voltage differential signal....
